J Neurosci
. 2023 Jun;
43(29):5378-5390.
PMID: 37369590
Radial frequency (RF) patterns, created by sinusoidal modulations of a circle's radius, are processed globally when RF is low. These closed shapes therefore offer a useful way to interrogate the...

Clocks Sleep
. 2022 Oct;
4(4):577-594.
PMID: 36278538
Light is an influential regulator of behavioural and physiological state in mammals. Features of cognitive performance such as memory, vigilance and alertness can be altered by bright light exposure under...

Brown H, Gouws A, Vernon R, Lawrence S, Donnelly G, Gill L, et al.
Brain Struct Funct
. 2021 Sep;
226(9):2855-2867.
PMID: 34529124
Macular degeneration (MD) causes central vision loss, removing input to corresponding representations in the primary visual cortex. There is disagreement concerning whether the cortical regions deprived of input can remain...

Fritsche M, Lawrence S, de Lange F
J Neurophysiol
. 2019 Nov;
123(1):224-233.
PMID: 31774368
The visual system adapts to its recent history. A phenomenon related to this is repetition suppression (RS), a reduction in neural responses to repeated compared with nonrepeated visual input. An...

Lawrence S, van Mourik T, Kok P, Koopmans P, Norris D, de Lange F
Curr Biol
. 2018 Oct;
28(21):3435-3440.e4.
PMID: 30344121
The human primary visual cortex (V1) is not only activated by incoming visual information but is also engaged by top-down cognitive processes, such as visual working memory, even in the...

Keefe B, Gouws A, Sheldon A, Vernon R, Lawrence S, McKeefry D, et al.
Hum Brain Mapp
. 2018 Jul;
39(10):3813-3826.
PMID: 29968956
Symmetry is effortlessly perceived by humans across changes in viewing geometry. Here, we re-examined the network subserving symmetry processing in the context of up-to-date retinotopic definitions of visual areas. Responses...

Neuroimage
. 2017 Jul;
197:785-791.
PMID: 28687519
The cortex is a massively recurrent network, characterized by feedforward and feedback connections between brain areas as well as lateral connections within an area. Feedforward, horizontal and feedback responses largely...

Vernon R, Gouws A, Lawrence S, Wade A, Morland A
J Neurosci
. 2016 May;
36(21):5763-74.
PMID: 27225766
Unlabelled: Representations in early visual areas are organized on the basis of retinotopy, but this organizational principle appears to lose prominence in the extrastriate cortex. Nevertheless, an extrastriate region, such...

J Vis
. 2016 May;
16(7):17.
PMID: 27191945
Individual radial frequency (RF) patterns are generated by modulating a circle's radius as a sinusoidal function of polar angle and have been shown to tap into global shape processing mechanisms....
